Chen, Fuqiang & Wu, Chunsheng, 2019, A taxonomic review of the genus Eoophyla Swinhoe, 1900 (Lepidoptera: Crambidae: Acentropinae) from China, Zoological Systematics 44 (3), pp. 212-239 : 225-228

Eoophyla ciliensis sp. nov. ( Figs 33–34 , 41–42 )

Diagnosis. The species is very similar to E. sinensis in both external and genital characters, but has obvious smaller size not only in external but also in genital. In adult, the new species has the fuscous triangular patch in forewing connected with postmedial fascia rather than touched in E. sinensis . Moreover, the white patch surrounding by the triangular patch and postmedial fascia in forewing and the white area between ante- and postmedial fasciae in hindwing are obviously smaller than those in E. sinensis . Besides the size, the new species also has the uncus more pointed than E. sinensis and different shape of juxta in male genitalia.

Description. Wing span ♂ 21 mm (n = 1), ♀ 26 mm (n = 1). Head pale fuscous; antennae filiform, base with a side projection present in male; labial palpi upturned, as long as compound eyes, densely suffused with long scales in ventral. Thorax and abdomen brown. Legs and tarsi slender.

Male. Forewing brown, little paler in basal half; upper edge of cell diffused with fuscous long setae in basal half and androconial hairs covered with apical 1/3 of cell from upper edge; a longitudinal brown fasica arising along inner margin; a triangular fuscous patch beyond discocellulares, with outer edge slightly bended, connected with postmedial fascia; postmedial fascia band-like, fuscous; submarginal fascia band-like, yellow, with fuscous edges on both sides; cilia fuscous. Hindwing with base white; antemedial fascia brown; postmedial fascia brown, with fuscous edges on both sides; an incision present below apex; three eyespots present along outer margin, with silvery scales centrally; submarginal fascia band-like, yellow, with fuscous edges on both sides; cilia fuscous. Female same with male except androconial hairs absent.

Male genitalia ( Fig. 41 ). Uncus slender, with apex pointed; gnthos about 4/5 length of uncus, apex with several dorsal teeth; tegumen with sclerotized dorsal ridge X-shaped; valva densely covered with setae, nearly same width from base to apex, three strong specialized setae present at apex, about 3/4 length of valva, third seta with minute spines laterally and a knife-shaped apex; vinculum broad; saccus round; juxta plate-like, with apex bifid; aedeagus slender, vesica with many minute spines, ductus ejaculatorius arising from middle.

Female genitalia ( Fig. 42 ). Anal papillae relatively broad, densely covered with setae; apophysis anterioris and posterioris near same width, about 1.5 times length of anal papillae; antrum elongated, cylindric; collar sclerotized; ductus seminalis arising below collar; ductus bursae about half length of coupus bursae, with many minute spines; corpus bursae membranous, a pair of signa present, consisting of minute spines, about 3/4 length of corpus bursae.
